nVision - Reference Recorder

Accurate enough to replace a deadweight tester
Rugged enough to sit in 3 feet of water
Portable enough to complete calibrations anywhere

nVision lets you visualize measurements graphically, with or without a pc, in real time as it is being recorded.  It is much easier to identify trends or anomalies visually, than in tables of data or spreadsheets.

• Gauge / Absolute Pressure Datalogger to 15 000 psi / 1000 bar / 100MPa
• Differential Pressure with up to 0.025% of reading accuracy 
• Switch, Voltage, Current, and Temperature
• 500 000 data points - 10 readings per second from 2 modules

There’s never been anything like this! 

• Connects to a PC to view live readings or export to tamper proof digital records
• Compensates accuracy for temperature effects from -20 to 50°C
• Includes a calibration certificate with test data at 5 different temperatures from our A2LA accredited laboratory
